King of Cards Slot Configuration

I see King of Cards as a classic casino machine with 5 reels and 9 pay lines coming from Greentube. It looks like a simple pokie, yet it comes with lots of extra spins and winning opportunities suitable for every gambler. The online machine has a basic menu where all functions can be adjusted with a few mouse clicks, so I can quickly press the Bet One button to increase or decrease my wager.

To change the number of lines in King of Cards, I just click on one of the five offered buttons, and if I feel bold there is the Max Bet mark that sets stakes automatically to the maximum. Rounds can be started manually by hitting the Spin icon or set to run with the Autospin button, which stops by itself when a free spinning bonus is triggered, and full rules sit in the Paytable window.

Gaming Symbols and Bonus Spinning in King of Cards

While playing King of Cards, I see lots of basic signs like playing cards and suits spinning across the five reels, yet the icon that really matters for me is the wild card. This symbol brings the highest payout in the online game and can substitute all signs except for the scatter icon, so whenever a wild joins a winning line it doubles the score and can turn a modest spin into a solid result.

The other special card in King of Cards is the scatter symbol, and my goal is always to get three or more of them on the screen to trigger the free spinning feature. Hitting that trigger brings 15 free rounds, and during these extra turns a multiplier times three stays active, so every win grows, and in my experience those stretches of free games can produce some of the most exciting payouts on this pokie.

Bonus Rounds & Features in King of Cards

In King of Cards, the Gamble Feature appears after each winning spin, and I can either take my winnings or risk them in a mini-game and gamble up to x5. When I choose to play, I just click on the bet one button and face a simple setup with a face-down playing card, where all I need to do is guess the colour, knowing that one wrong guess wipes the whole amount.

I like how King of Cards combines this risk with the Doubling Wild Feature, since the wild symbol does not just substitute for regular icons but also doubles the prize when used for substituting. When that Joker playing card lands in a winning combination, the line win grows, and if I then decide to send those doubled winnings into the Gamble Feature, the pressure rises quickly across a few bold guesses.

The Free Games Feature in King of Cards keeps things lively, as three scatter symbols anywhere on the screen award 15 free spins with x3 multipliers on every win. I enjoy chasing retriggers during these sessions, since free games can be won again under the same conditions, so a single run of stacked poker chips can stretch into a long series of spins where every prize is multiplied three times.

Available Bonus Symbols in King of Cards

For me, the key bonus symbols in King of Cards are very clear, starting with the wild symbol shown as a Joker playing card. This wild pays up to 9,000 coins if I manage to receive five of them together, substitutes for all symbols except scatter, and doubles the prize whenever it steps in, while the scatter, drawn as a picture of stacked poker chips, pays up to 500 coins anywhere and activates those all-important free games.

Best Winning Tips for King of Cards

I treat King of Cards as a low to medium volatility casino game where I can bet with low-risk chances, helped by RTP around 95 per cent. Slot machines are games of luck and chances, so I do not rush, as odds of scoring can simply be enhanced by playing longer, setting the wheel of luck to spin automatically, pressing the max bet button, and always keeping all lines turned on for more winning chances.

My favourite approach in King of Cards is to aim scatter cards at every stage, as spinning the wheel for free is a chance to win real money prizes without placing stakes, so during those extra turns I can just lay back while the wheel is spinning. This casino game provides the same chances for every gambler, playing budget has no influence, and the slot can be mastered by a total beginner using a demo version.
